Operating speed precision in steady state: ≤±0.5% rated
synchronous speed
Torque response: ≤50ms VC, SVC, FVC ≤20ms
Motor Parameter
Self-measurement
Being able to detect parameter automatically under static
state and dynamic state of motor, thus guarantee an optimum
control.
Current and Voltage
Restrain
Current closed-loop control, free from current impact, perfect
restrain function of overcurrent and overvoltage
Undervoltage
Restrain
during
Running
Specially for users with a low or unsteady voltage power grid: even lower than the
allowable voltage range, the system can maintain the longest possible operating time based
on its unique algorithm and residual energy allocation strategy
Multi-velocity
and Traverse
Operation
16 segments programmable multi-velocity control, multiple operation mode. Traverse
operation: preset frequency and center frequency adjustable, parameter memory and
recovery after power cut.
PID Control
RS485
Communicatio
n
Built-in PID controller (able to preset frequency). Standard configuration RS485
communication function, multiple communication protocol for choice, synchronizing
control function.
Direct voltage 0~10V, direct current 0~20mA (optional up
limit and lower limit)
Operation panel setting, RS485 port setting, UP/DW
terminal control, or combined with analog input
2 channel OC output and 2 channel relay output (TA1, TB1,
TC1/TA2,TB2,TC2), up to 16 choices
2 channel analog signal output, output ranging within
0~20mA or 0~10V with flexibly setting, achievable output
of physical quantities like set frequency, output frequency
